The level of retinal KIF11 was dramatically decreased upon injection with KIF11‐shRNA adenoviruses (Figure 1c), as intravitreal injection has been demonstrated to efficiently deliver adenovirus particles to photoreceptors (Figure S1a, Supporting Information).[12, 18] Fundus photography, a clinical tool frequently used for the evaluation of retinopathies,[19] was performed to analyze retinal structures in these mice. Here, KIF11 is linked to retinal disorder.
